LEVER-POWER ENGINE.

SPECIFICATION forming part of Letters Patent No. 483,776, dated October4, 1892.

Application filed May 23, 1892. Serial No. 434,106. (No model.)

To all whom it may concern:

I 3e it known that I, ALLEVI ANNIBALE, a citizen of the United States,residing at Chicage, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Lever Power Engines, ofwhich the following is a full, clear, and exact specification.

My invention relates to that class of motors known as lever-powerengines, so called because of the levers embodied or employed thereinfor converting the rapid motion of some suitable driving motor or engineinto greater power.

In lever-power engines as heretofore constructed the driving-motor inperforming its function not only has to supply motion to the lever forcausing it to act upon the driven shaft, but, in addition, has to raisesuch lever into position. for action, and as the levers are usually Verylong and weighty the loss of power thus entailed is considerable.

The prime object of my invention, therefore, is to construct an improvedpower-engine in which the lever or levers shall always be inequilibrium.

A further object of my invention is to utilize the movement or stroke ofthe levers in both directions.

A still further object of my invention is to provide the lovers with atraveling fulcrum and to have the strain upon such fulcrum'at all timesequal, and equal only to the weight of the levers and parts supported onthe latter.

With these ends in view my invention consists in certain features ofnovelty in the con struction, combination, and arrangement of parts bywhich the said objects and certain other objects of minorimportancehereinafter described are accomplished, as fully explained withreference to the accompanying drawings, and more particularly pointedout in the claims.

In the said drawings, Figure 1 is a side elevation of my improvedengine, showing the belt by means of which motion may be transmittedthereto from any suitable motor or engine (not shown) and another beltby means of which the power of the lever-engine may be employed or putto use. Fig. 2 is a plan view of the same; and Fig. 3 is a verticaltransverse section taken on the line 3 3, Figs. 1 and 2.

Like signs of reference indicate like parts throughout the severalviews.

In carrying out my invention I employ a frame or bed 1 of any suitabledesign and construction, upon which is mounted in suitable journal-boxes2 a crank-shaft 3, on one end of which is secured a pulleywheel 4, Whileon its other end or other convenient place may be mounted an ordinaryflywheel 5 for keeping up the momentum of the shaft 3, as will beunderstood. To the crank 6 of this shaft 3 is attached a doubleorbifurcated connecting-rod 7, whose bifurcations are pivoted at theirlower ends, respectively, to two horizontal levers 8, the latter beingfulcrumed on pins or pivots 9, journaled in suitable boxes 10, mountedupon the standards 11 or other fixed portion of the frame or bed.

Journaled upon the bed or frame 1, above the levers S, in suitablejournal-boxes 12, is a shaft or pin 13, which constitutes a fulcrum fortwo crossed levers 14 15, such pin or shaft 12 passing through suchlevers preferably midway of their length. The upper ends of the levers14 15 are connected together by two links 16 17, which are pivoted tothe le vers 14 15, and are themselves connected or pivoted together attheir upper ends, and the lower ends of the levers 14 15 are similarlyconnected together by similar links 18 19,the links 16 17 and 18 19being connected, respectively, to the main power-levers 20 21 by anysuitable means. Thus it will be seen that the weight of the lowerpower-lever 21 pulling downward upon the levers 14 15 will have atendency to bring such levers into a parallel position and force theupper main powerlever 20 upward; but as this latter lever is equal inweight to the lever 21 it is obvious that it will exactly counterbalancesuch lever 21, and the two levers in consequence will remain inequilibrium in whatever position they might be placed. It will also beseen that when the levers 14 15 approach a parallel position they willcause the divergence of the main power-levers 2O 21, and, owing to themanner in which said levers 14 15 are connected to the mainpower-levers, the motion imparted to the latter by the levers 14 15 willbe very great as compared with the movement of the levers 14 15. As ameans of applying motion to these levers 14 from the crankshaft 3, Iconnect such crank-shaft through the medium of the connecting-rods 7 andthe levers 8, already described, to one of the levers 14 15 by means ofan arm or link 22. As shown in the drawings, such link 22 is pivoted atone end to the lever 15 about midway of its upper half and at its lowerend to the levers 8 at or near their outer extremities. Thus when thecrank-shaft 3 is rotated a reciprocating motion will be imparted to thearm or link 22, which will cause the levers 14 to oscillate to and fromeach other and produce the desired movement to the main' power-levers 2O21 through the connections before referred to.

I have shown in the drawings, and I prefer to use duplicates of thelevers 14 15, as illustrated more clearly in Fig. 3, and also duplicatesof the links 16 17 and 18 19, as well as of the arm 22. The links 17 maybe pivoted between the links 16 on a suitable pintle or shaft 23, andbetween the levers 15 on a similar pintle 24, and the levers 14 arepreferably arranged between the levers 15, so that a suitable elasticbumper 25, arranged on the shaft or pintle 26 between the levers 15,will strike against the lower ends of the levers 14 when the levers 2O21 come together, thus avoiding undue jar and also imparting to thelevers 14 15 a tendency to assume a vertical or upright position. Thelinks 19 are pivoted to the lower ends of the levers 14 on a suitablepintle 27', and the links 18 are pivoted to the levers 15 by pintle 28and to thelevers 19 by pintle 29, the main power-levers 20 21 beingpivoted on the pintles 23 29, respectively. WVhile I have beenparticular to describe these parts as double, it will nevertheless beunderstood that it would not involve a departure from the spirit of myinvention to use single links, levers, and arms as they appear in sideelevation in Fig. 1 instead of the double parts, such duplication beingemployed simply for the sake of greater strength and rigidity in thestructure.

The main power-levers 2O 21 are fulcrumed at the upper and lower ends,respectively, of the upright brace 30, which is provided with atransverse shaft 31, constituting a crosshead sliding upon any suitablerunway mounted upon the frame or bed 1. The ends of this shaft 31, ifdesired, may be provided with antifriction-rollers 32, having groovedperipheries engaging the upper and lower bars 33, constituting therunway. The short arms 34 35 of the levers 20 21, respectively, areconnected togetherby a knuckle-joint 36, consisting of two links pivotedto the ends of the levers 2O 21, respectively, and connected together bya shaft 37, which constitutes a second cross-head and whose ends areprovided with rollers 38 similar to the rollers 32, which play back andforth between the bars 33. Thus it will be seen that when the mainpower-levers 2O 21 oscillate to and from each meme other they will havea bodily movement onthe rollers 32, incident to the rising and fallin gof their pivots 23 24, in a strictly vertical plane, and, in addition tothis movement, the cross-head or shaft 37 will have an independentforward and backward movement, due to the oscillations of the linksconstituting the knuckle-joint 36. Hence it will be seen that themovement of the crosshead 37 will be equal to its own individualmovement induced by the knuckle-joint 36 plus the bodily movement of thelevers 2O 21, resulting from the oscillation of their rear ends in astraight line. In order to utilize the power focused at the cross-head37, I connect such crosshead to the crank-shaft 39 by means of asuitable connecting-rod 40, so that the power of the cross-head 37 maybe transmitted to any desired machinery through the medium of a suitablepulley 41, mounted thereon,and belt 42 or other well-known form ofgearing. The reciprocating connecting-rod may be provided with an eye 43to permit the passage of the shaft or cross-head 31, and to allow suchrod to be reciprocated by the movement of the cross-head 37 and tooscillate with the crank 44 of the shaft 39.

The cranks 6 and 44 are arranged on the quarter, as more clearly shownin Fig. 1, and

in order that they may retain this position with relation to each otherI provide each of the shafts 3 39 with the sprocket-wheel 45 46,respectively, and connect these sprockets together by means of thesprocket-chain 47, thus preventing the cranks from getting on adeadcenter and also insuring the rotation of the crank-shaft 39 in theproper direction, it being of course understood that the stroke of thecrank 6 is greater than that of the crank 44.

The levers 8 may be provided with a num ber of holes or perforations 48to permit of variation in the relative length of the arms of suchlevers, and, if desired, the augmentation of this variation may be madepossible by 10- cat-ing the crank-shaft 3 closer to the crankshaft 39and employing levers 8 of greater length.

Motion may be imparted to the crank-shaft 3 through the medium of asuitable belt 49, connected to any appropriate source of power or motor,such as a small gasengine or the like. (Not shown.)
